Answer 1

Hint:
It is given that shanu has scored 320 marks out of 400 marks and the percentage acquired is given by $\dfrac{{{\text{marks scored by shanu}}}}{{{\text{total marks}}}} \times 100$

Complete step by step solution:
We are given that shanu has secured 320 marks out of 400
The percentage is given by $\dfrac{{{\text{marks scored by shanu}}}}{{{\text{total marks}}}}\times100$
Here the marks scored by shanu is 320
And the total marks is 400
$
   \Rightarrow \dfrac{{320}}{{400}}\times100 \\
   \Rightarrow 80\% \\
$
Therefore the percentage acquired by shanu is 80%.

Note:
1) Percentages are one way of writing numbers; you can also write percentages as fractions or decimals.
2) In mathematics, a percentage (from Latin per centum "by a hundred") is a number or ratio expressed as a fraction of 100.
